Answer:
Since the question is missing most of its numbers, I looked for similar question.
variable cost per unit = $1,015,000 / 73,000 = $13.9041
total fixed costs = $490,000
since fixed costs are not avoidable, but can be used to generate $220,000 in revenues, the differential analysis is the following:
Make Buy Net income increase
(decrease)
variable costs $1,140,136.20 $0 $1,140,136.20
fixed overhead $490,000 $270,000 $220,000
purchase price $0 $1,066,000 ($1,066,000)
total $1,630,136.20 $1,336,000 $294,136.20
TechSystems should outsource the production since it will be able to increase its operating profits by $294,136.20.
